Update Cluster Configuration

To update the cluster configuration, you can use one of the following methods:
In the cluster provision process, when you select a release channel, you can choose to enable or disable the cluster features and protocols based on your requirements. You can also click the “Add optional custom configuration” to set custom cluster settings for your Pulsar cluster.Configure ClusterAfter cluster is provisioned, you can view the current cluster configuration through the “Configuration” page of your Pulsar cluster. You can also update the cluster configuration by clicking the “Edit Cluster” button at the top right corner of the page. You will be redirected to the same configuration page you see in the provision process, where you can make the desired changes to the configuration options.Cluster Configuration
Please note that not all configuration options are modifiable. Some settings are determined by the release channel you selected during the cluster provision process and cannot be changed. Updating the cluster configuration will cause the cluster to roll restart all the brokers. Please make sure to update the cluster configuration during off-peak hours to avoid any disruptions to your service.
